Abstract:
A beverage machine has a gas dissolution assembly that includes a pressure vessel having an open end and a top cap that couples with the open end of the pressure vessel. The top cap has a gas inlet through which a gas to be infused into the beverage flows. A clamping mechanism clamps the top cap onto the open end of the pressure vessel. A gas infusing device that is coupled to the gas inlet has a porous element that infuses the gas into the beverage.
Abstract:
A system for strain gage calibration includes a data acquisition system operable to receive sensor inputs from a force sensor as a force input and a strain gage as a strain output. The strain gage detects a strain measurement of a structure under test in response to an excitation force applied by an excitation device, and the force sensor detects the excitation force. The system also includes a data processing system operable to perform calibration feature extraction of a plurality of calibration features from time and frequency domain responses of the force input and the strain output, and to determine a calibration factor of the strain gage based on a correlation of the calibration features to reference calibration features. The force input and the strain output are preprocessed before the calibration feature extraction to filter noise, remove outlying data, and temporally align the force input and the strain output.
Abstract:
A force applicator assembly (10; 10') is disclosed to calibrate an in-situ force transducer (or load cell) (104) in a force (load) applying test machine (125). The force applicator (10) includes stationary member (22; 22') configured to be secured to fixed structure, a moving member (20; 20'), a load cell (12) operably coupled to an end of the moving member (20; 20'); and a differential screw assembly (24; 24") connecting the moving member (20; 20') to the stationary member (22; 22'). A coupling assembly (14) can be used to assure that only tension or compression loads are applied. The coupling assembly (14) can be configured if desired such that no tension or compression loads can be applied. A method to calibrate an in-situ force transducer (104) in a force applying test machine (205) is also provided and uses a force generator (16; 16'; 125) and the coupling assembly (14).

Abstract:
A system for measuring a chain parameter of a moving chain is provided, wherein the chain has a repetitive structure such as a chain link or teeth in a cogged belt. The system comprises at least one optical sensor positioned and configured to receive light from the moving chain, and a processor functionally associated with the optical sensor. The processor is configured to obtain from a signal stream received from the optical sensor a chain parameter characterizing the chain while the chain moves. An Image Monitoring Unit (IMU), comprising the optical sensor, may be assembled proximal the chain of a bicycles or of a spin bike, and a Human Computer Interface (HCI) unit comprising a display and functionally associated with the IMU, allows a user to view measurement results of a chain parameter and to operate the system. A method of measuring a chain parameter of a moving chain is also provided.
Abstract:
A product testing assembly is described. The product testing assembly may include a substrate, a measuring device, and a data processing system. The substrate has at least one surface configured to receive an application of a product to be tested, for example paint. The measuring device is configured to sense measured quantities as product is applied to the substrate and output one or more signals representative of a sequence of forces and/or moments being applied to the surface of the substrate by the application of the product to be tested. The data processing system has one or more processors configured to receive the one or more signals representative of the sequence of forces and/or moments being applied to the surface of the substrate, and to convert the one or more signals into an output signal representative of one or more application performance characteristics of the product to be tested.
Abstract:
A method for aligning an optical measuring system comprises the provision of an optical measuring system having the following as optical elements: a beam splitter; a first photo sensor, on which a first sub-beam from the beam splitter impinges; an optical filter; and a second photo sensor lying behind the optical filter in the beam direction, a second sub-beam from the beam splitter impinging on said sensor. The angular position and relative position of a number of the optical elements to one another can be aligned. The method further relates to: the provision of a device for forming a differential signal from the signals of the two photo sensors; the provision of a light source having a polarisation that modifies over time and the irradiation of light into the beam splitter such that a single sub-beam impinges on each photo sensor; the formation of a differential signal from the output signals of the photo sensors; the variation of the position and/or angular position of at least one of the optical elements and the monitoring of the differential signal; the determination of the angular positions/ position of said elements in which the differential signal has a minimum value and the setting of the angular positions of the optical elements according to the determined values. The invention also relates to a corresponding system.
